Title:
COMMUNICATION SYSTEM, LIST REFERENCE STATION, LIST DISTRIBUTION STATION, COMMUNICATION METHOD, AND COMMUNICATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/105130
Kind Code:
A1
Abstract:
A list reference station (200) of a communication system (500) is provided with: a list recording unit (205) that records, in a memory, a ground master list (20) including the station number of a ground master and the station numbers of communication stations synchronized with the ground master; and a reference time correction unit (203). The reference time correction unit (203) receives, from another communication station, a time distribution frame (22) including time information for synchronizing the times of a plurality of communication stations. The reference time correction unit (203) determines whether or not the station number of the communication station from which the time distribution frame (22) has been transmitted is the station number of the ground master included in the ground master list (20). If the station number of the communication station from which the time distribution frame (22) has been transmitted is the station number of the ground master included in the ground master list (20), the reference time correction unit (203) corrects the time of the station in which the reference time correction unit (203) is provided by using the time information included in the time distribution frame (22).
